CVE-2019-1790
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker with valid administrator credentials to execute arbitrary commands on the underlying operating system of an affected device.
Does this matter?
Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.
Description
A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker with valid administrator credentials to execute arbitrary commands on the underlying operating system of an affected device. The vulnerability is due to insufficient validation of arguments passed to certain CLI commands. An attacker could exploit this vulnerability by including malicious input as the argument of an affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with elevated privileges. An attacker would need valid administrator credentials to exploit this vulnerability.
